Kudos to the state for action taken to keep our air less noxious. Smelling the odiferous wafts of smoke from coal-burning stoves while driving along Farmers Loop recalled memories of a much earlier Fairbanks when the predominant heat source was coal-fired, creating a winter-long Dickensian pulmonary environment.
Emissions from coal-fired heat source stoves also are poisonous. There are three major sources of arsenic in air: smelting of metals; burning of coal, vegetation and agricultural wastes; and use of arsenical pesticides, with burning of coal being the most noxious.
A safe exposure limit of arsenic is considered to be 20 nanograms per cubic meter of air. Living with some types of coal fires within a domestic coal-burning area may expose you to more than 90ng/m3 as an annual average.
Thank you, thank you, thank you.
